Cartografía de zonas vulnerables a la erosión hídrica con la ayuda del método PAP/CAR y SIG en relación con la presa Allal el Fassi, Atlas Medio

Abstract: RÉSUMÉLe présent travail a pour objectif d'étudier l'érosion hydrique dans les deux bassins de Beni alaham et Al azhar situés au moyen Atlas, et de les hiérarchiser en parcelle selon le degré érosif à l'aide De l'approche PAP/CAR qui portait surtout sur l'intégration des facteurs influençant l'érosion hydrique, tels que la pente topographique qui traduit la morphologie et l'inclinaison des terres, le réseau hydrographique, le type de sol et le matériel lithologique, le type de couverture végétale qui traduit l… Show more

“…The significant lower class of erosion in this part of the basin is very small and limited to the entourage of moderately deep ravines. This same observation is made in the watershed of Wadi Larbaa where areas with low and moderate erosion, coinciding the sheet erosion, especially at the edge of the wadi and it are explained by the absence of vegetation cover [7].…”

“…Several methods and models are developed, and among these models, the PAP/RAC (Priority Actions Programme/Regional Activity Centre) guidelines are the most suited to the Mediterranean conditions. The application of this model in other watersheds of the Moroccan territory, to know the watershed of the Wadi Larbaa [6], Allal El Fasi [7], Sahla [8] and Asfalou River [9] shows the reliability of this model applied.…”

“…In the field, the qualitative assessment of erosion was conducted by estimating the "soil surface factor" (SSF). The SSF, ranging from 0 to 100, is an index that assesses the state of degradation of a slope (plot) by water erosion [14,15]. It consists of observing the plot and assigning values to the degrees of the factors linked to the erosion process, thus making it possible to classify the plots by the degree of erosion: soil movement, surface litter, stones on the soil surface, witnesses of erosion, flow model, ravines, and gullies.…”
